   FANTASY THEME (dark green palette)

   Applied whenever body.fantasy-theme is set (toggled in
   script.js alongside the Sci-Fi / Fantasy genre switch).
   Mirrors the RELATIONSHIPS between the default dark-blue
   palette's variables (background depth, text contrast,
   accent/button hierarchy) rather than reskinning a single
   color — every var that the default palette defines is
   redefined here with a forest-green / emerald equivalent.
